HARASSMENT BY GAME STORE

Gooday, on the 28 May I asked for a settlement amount of which it was sent to me and the amount was paid within 10days as required. Game has been sending me notification for payment on the settled accounts. I went to Ilanga mall branch and enquired about the account and I was told that it shows that I donot owe they will fix it. Now am getting notification that the account has been handed over to Collection or I must pay 315. 00. I have proof od payment and the settlement sms that was sent to me. PLS GAME STOP HARASSING ME.
